TJSIG system software is the first self-developed software in my country that is used for urban road traffic design and intersection signal timing optimization and provides complete data analysis. Based on the research results of the National Natural Science Foundation of China, the system integrates traffic design theory, traffic signal control theory and traffic system evaluation theory. It is suitable for the evaluation and analysis of traffic design, capacity and service level of new road intersections._；It can also evaluate and improve existing intersections, provide necessary decision support for urban construction design and traffic management departments, and completely change the boring and cumbersome work of traditional traffic design and signal timing.

TJSIG can dynamically generate intersection traffic design diagrams and signal timing phase sequence parameter diagrams. It has dual optimization and mutual feedback functions of spatial design and time design; supports "phase overlapping nesting" and allows users to customize the phase sequence according to traffic needs; Fully consider the traffic safety and efficiency of bicycles and pedestrians under my country's mixed traffic conditions; reserve the interface between public transportation priority and control modules; and have dual functions of optimization generation of plans and evaluation of established plans; Provide six optimization objective functions; provide analysis reports of up to nine intersection design evaluation indicators.<o></o>
